In this paper, a deep learning-based prediction model VMD-GLRT is proposed to address the accuracy problem of service load prediction. The VMD-GLRT model combines Variational Mode Decomposition (VMD) and GRU-LSTM. At the same time, the model incorporates residual networks and self-attentive mechanisms to improve accuracy of the model. The VMD part decomposes the original time series into several intrinsic mode functions (IMFs) and a residual part. The other part uses a GRU-LSTM structure with ResNets and Self-Attention to learn the features of the IMF and the residual part. The model-building process focuses on three main aspects: Firstly, a mathematical model is constructed based on the data characteristics of the service workload. At the same time, VMD is used to decompose the input time series into multiple components to improve the efficiency of the model in extracting features from the data. Secondly, a long and short-term memory (LSTM) network unit is incorporated into the residual network, allowing the network to correct the predictions more accurately and improve the performance of the model. Finally, a self-focus mechanism is incorporated into the model, allowing the model to better capture features over long distances. This improves the dependence of the output vector on these features. To validate the performance of the model, experiences were conducted using open-source datasets. The experimental results were compared with other deep learning and statistical models, and it was found that the model proposed in this paper achieved improvements in mean absolute percentage error (MAPE).
The urban cockpit will comprehensively perceive and process all kinds of data in the city operation, establish the data chassis of the smart city, objectively, comprehensively and multi dimensionally display the operation situation of the city, and carry out early warning, prediction and scientific disposal of outstanding problems and emergencies in the city operation. Moreover, in the near future, with the introduction and use of 5G, artificial intelligence, big data, data Luan Sheng and edge computing in the city brain project, the city cockpit will also give the city managers and visitors a better and more beautiful feeling in the display effect (such as immersion and three-dimensional), thus accelerating the promotion and landing of the city brain project and promoting social governance Intelligent and professional, improve the level of comprehensive city governance, and change the transformation and upgrading of the city from extensive to precise and refined.
